Application filed August 18, 1926. Serial No. 129,982.

This invention relates to air purifier apparatus particularly adapted for use on aeroplanes, the intent being to provide a purifier which may be used for removing or counteracting poisonous gases when flying in a poisonous air area, the construction embody-' mg enclosed control and engine compartments to which the purified air is supplied when conditions demand it, whereby the operators of the aeroplane will not be subjected to the poisonous gases. The invention may be utilized under certain other condition with aeroplanes. ne form thereof is disclosed in .the accompanying drawings, in

which Fig. l is a plan of an aeroplane equipped with the apparatus. Fig. 2 is a section on the line 22. of Fig. 1. Fig. 3 is a detail in plan of the purifier strainer. Fig. 4 is an end view of Fig. 3.

The aeroplane fuselage 5 has an enclosed engine compartment indicated at 6 and an enclosed control compartment indicated at 7, and an air purifier compartment indicated at 8 in the rear of the control compartment. A. U-shaped frame 9 is secured in compartment 8 and has horizontally spaced canvas screens 10 secured thereto and extending horizontally across the same. The compartment 8 has a water tight cover 11.

A pump indicated at 12 is driven off the engine shaft and is adapted to pump heated water from a casing 13 which is heated by the engine exhaust, thru a pipe 14 to the compartment 8 and is adapted to maintain a suitable depth of water in said compartment, say about one-third full. The circulation return to the heater is indicated as a pipe 15. The pump 12 is a multiple pump which, in addition to pumping water thru the pipes 14 and 15, also pumps air thru a pipe 16 and valve 17 at the bottom of compartment 3, as shown in Fig. 2, and thence thru a valve 18 into the control compartment 7 and thence thru a valve 19 into the engine compartment 6, these valves being located in the walls between the respective compartments, the valve 18 being located in compartment 8 above the water level therein. The engine and control compartments 6 and 7 have air outlet valves 20 and 21 in the top thereof. Instead of water alone, the liqpid circulated thru the compartment 8 may have suitable chemicals dissolved therein to counter-act poison gas; and the pipe 16 may have a suitable shunt valve 16 to shunt the air thru the control and engine compartments without passing it thru the purifier. .In operation, the water section of pump 12 circulates the water thru the pipes 14 and 15 and the compartment 8, in its circulation the water being heated at the exhaust head 13. At the same time air drawn in by the air section of pump 12 will be forced thru the pipe 16 and valve" 17 and will bubble up thru the liquid in compartment 8, the air being thus purified or its poisonousconstituents nullified, after which it passes thru the canvas screens 10 and is forced thru the valve 18into the control compartment and thru the valve 19 into the, engine compartment, whence it escapes thru the outlet valves 20 and 21. Y 1 It will be understood that the controlcompartment at least may be provided with suitable glasses or hoods so that theopere available for use in an engine compartment, a control compartment, and .an air purifier compartment, valves between said compartments, and meansto conduct anthru the air purifier compartment and thru said valves into the other compartments.

2. An aeroplane having an engine compartment with an engine therein, a control compartment, and an air purifying compartment, said compartments communicating with each other, and means driven by the engine to force air into said air purifying compartment and from the same into th other compartments.

3-. The combination stated in claim 2, the air purifying compartment containing a body of liquid thru which the air passes, and means to heat said liquid. from the engine exhaust.

In testimony whereof, I do aflix my signature.
